This project will assess how corn responds to nitrogen at various levels of potassium fertilization.

Nutrient management dynamics in Northwest Minnesota corn production (Year 2)
This project will address the combined effects of fertilizer source and rate on nitrogen, phosphorus, and carbon dynamics from multiple perspectives: corn grain production, soil nutrient availability, and water quality.
Dialing in the Most Corn-Profitable and Environmentally Responsible Nitrogen Rate (Year 3)
The study will use the common approach to calculate EONRs by establishing several nitrogen rates from zero to well above where a corn response is expected.
Irrigation management impacts on corn yield and nitrate leaching
The environmental impact of irrigated agriculture on ground and surface water resources in Minnesota is of major concern. Better irrigation scheduling has the potential in addressing these complex agricultural environmental challenges we face in Minnesota.
Reducing reactive nitrogen loses from corn systems
Over the last several years our regional atmospheric measurements and mesocosm experiments have revealed that reactive nitrogen losses associated with corn production are likely to increase as our climate continues to get warmer and wetter.
